LUBRICA'I'OR.

Specification of Letters Patent.

' Patented Sept. 8, 1914.

more particularly to a device of this general character operable under pressure; and the object of the invention is to provide a device of this general character having novel and improved means whereby the drop tube or feeding nozzle may be blown out without the loss of lubricant.

The invention consists in the details of construction and in the combination and ar-- "be carefully defined in the appended claim.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the companying drawings, wherein- Figure 1 is a vertical sectional view taken through a lubricator, showing an embodiment of my invention applied thereto; and Fig. 2 is an enlarged sectional view taken through the valve'member included in my invention as herein disclosed.

As-disclosed in the accompanyin drawings, 1 denotes the body of a In ricator which may be of any ordinary or preferred construction and herein disclosed as having mounted thereabove the condensation chamber 2 provided with a suitable steam inlet 3 and having a condensation tube 4 extending downwardly within the body 1 of the lubricator and terminating in close proximity to the base thereof, the flow from the condensation chamber 2 to the tube 4 being under control of the valve 5 of any ordinary or preferred construction.

.As herein disclosed, the body 1 has suitably secured thereto, adjacent its lower end, the laterally disposed casing 6 having suitably connected therewith the oil pipe 7 the receiving end of which being located in close proximity to the top of the body 1 so that the oil or lubricant forced upwardly within the body will pass downwardly through such tube or pipe 7 into the casing 6.

Sdenotes a drain cock in the bottom of the body 1 of a construction substantially similarto that set forth in my prior Patent,

No. 905,057, dated November 24, 1908.

9 denotes a sight feed tube preferably formed of glass having its lower extremity suitably engaged with the casing 6 while the opposite or upper extremity thereof is suitably engaged with a tubular extension 10 projecting laterally from the body'l adjacent the upper end thereof and disposed in substantial continuity with the conduit 11 directed through the body 1 and adapted to be placed in communication in any conventional way with a suitable source of pressure supply and preferably steam.

The casing 6 is provided, as herein disclosed, with the upstanding drop tube or feeding nozzle 12 projecting within the feed member 9 and adapted to have projected therethrough the elongated member or conductor 14 formed of copper or other material and having the requisite rigidity. The

lower extremity of the member 14 is suitably engaged, as indicated at 15 in Fig. 2, with the valve member 16, having an axial opening disposed throughout its entire length, mounted for endwise adjustment through the nipple 17 projecting from the casing and adapted to close the flow of oil through the bores 18 and 19 of the casing 6 and tube 12,: respectively, and in order to maintain the major portion of the member 14 substantially alined with the axial center of the bore of the tubular valve member 16,. I provide the member 14 in close 1 by the water of condensation When the device is in operative position, the valve-member 16 is retracted to, open the ilow through the bores 18 and 19 whereby the oil' will be permitted to travel upwardly of the member 14: in a substantially uniform manner and result in the discharge of minute drops of oil which, in practical operation, has been found to be manifestly advantageous over similar devices wherein the drops of oil are comparatively large. Should the bore 19 of the tube 12 become clogged with sediment 01' from any other cause, it is only necessary to adjust the valve member 16 into closed position, as is shown 'in Fig. l, and whereupon the fiow of oil to within the member 9 is stopped. The petcook 20 is then opened and pressure admitted within the conduit 11 which, as is believed to be self-evident, will result in a thorough and effective blowing out of the bore 19 of the tube 12. readily perceived that by having the elongated member or conductor ll carried by and projecting upwardly from the valve memberlG and through the drop tube or feeding nozzle 9, the various movements of the valve member 16 will cause the member or conductor 14 to positively assure the bore 19 of the tube or nozzle 9 from becoming closed or unduly obstructed, as it will be observed that the member or conductor ll is of such a length as to be at all times directed entirely through the tube or nozzle 9, irrespective of the position of the valve member 16.

From the foregoing description, it is thought-to be obvious that a lubricator constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the conven- It will also be ience and facility with which it may be assembled and by reason of the effectiveness with which it performs its functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the prin oiples and spirit thereof and for this reason I do not wish to be understood as limiting 'myself to the precise arrangement and for- I mation of the several parts herein shown in.

justable through the casing and adapted to control the-flow through the tube, said valve member being provided with an axial opening throughout its entire length, independently operable means carried by the outer extremity of the valve member for controlling the flow therethrough, and an elongated member projecting through the tube, the lower extremity of said member being secured to the valve member within the bore thereof, said elongated member being provided in close proximity to the outer end of the valve member with an inwardl disposed offset whereby the major portion of the elongated member is positioned substantially at the axial center of the bore of said valve member.

In testimony whereof I hereunto affix my signature'in the presence of two witnesses. JOHN J. COSTELLO, JR. Witnesses:
